The ongoing postal strike could cost charities millions in donations, the South African Institute of Fundraising said on Saturday.
“The postal strike action over the past six months could mean a loss of R55 million to non-profit organisations delivering essential social services across the country,” said SAIF president Ann Brown in a statement.
“People do not respond to outdated mails; this exercise has been a waste of postage, paper and time.”
Last week, the SA Post Office’s (Sapo) board voluntarily resigned.
Telecommunications and Postal Minister Siyabonga Cwele said last Friday in a statement the board volunteered to resign to allow him to implement an intervention aimed at resolving issues at Sapo.
The strike has worsened the financial situation at the post office, which faces a R400 million shortfall as mail volumes continue to decline.
Unions are demanding an eight percent increase and the permanent employment of all casual workers.
Earlier this month, MPs were told the cash-strapped Sapo was on the brink of collapse.
